Unfortunately, I can't think of a way to do neutral ship-like objects.. That'd be for the asteroids, I suppose. The space hulk is kind of like that but you'll board them if you click them
Right, the "Weird Worlds 2: Return to Infinite Space for the Third Time: Ever Stranger Adventures in the Fourth Dimension" question... We haven't started anything yet, and there's no telling what we might do, and I kind of like that.
Weird Worlds does its thing pretty well so it's not likely we'll do the exact same kind of gameplay again soon. We could do something different in the Infinite Space universe, or something else entirely... I myself want to experiment with stuff like 3D and network programming when I have some free time.
